DA office is probably going to laugh then tell you no... I am not trying to be rude but it sounds like you want to carry an OTF then if you get caught just try to pawn it off as "I was deer hunting..." Not being mean but I have heard this from other Okies too... A lot of knife law is up to interpretation by Officer, Judge, and jury. This is not only true in OK but other places too. In Texas a man killed his wife with a large kitchen chefs knife and it was ruled that the knife was in fact a "bowie." Silly? yes... There is nothing wrong with buying them and collecting them, its just the law says you cannot carry one. I feel that Oklahoma needs to pass reform like Texas has to remove switchblade restrictions. As an Okie I can EDC a fixed blade of reasonable size as long as its not a bowie or dagger/double edged and no one blinks and eye. I also dont like when folks illegally carry an auto in Ok, (although most cops have better things to do then check your knife) Because it will only propagate the idea that they are solely weapons carried by lawbreakers further harming the cause of auto legalization. Plus there are much better assisted, manual, and fixed blades that you could carry that would serve you 100X better.
